Given numbers are 638,493,223

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 638,493,223 is 2418658.

Find LCM of 638,493,223 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

29 x 22 x 17 x 223 = 2418658

Therefore, the lowest common multiple of 638,493,223 is 2418658.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

638 x 493 x 223 = 70141082

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

638 : 1, 2, 11, 22, 29, 58, 319, 638

493 : 1, 17, 29, 493

223 : 1, 223

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,493,223, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

493:17x 29

223:223

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

29 = 29

Therefore, the value for common factors is 29.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 70141082/(1x29)

LCM = 70141082/29

LCM = 2418658

Thus, we can understand that the LCM of 638,493,223 is 2418658.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 504, 324, 784
• LCM of 547, 135, 284
